  K₂CO₃-Mediated, One-Pot, Multicomponent Synthesis of Medicinally Potent Pyridine and Chromeno[2,3-b]pyridine Scaffolds

  摘要：

  An efficient one-pot, multicomponent synthesis of 3,5-dicyanopyridines has been developed from the reaction of malononitrile and different thiophenol or thiols with a variety of aldehydes (aromatic including hindered ones, heteroaromatic, and aliphatic) in the presence of 20 mol% of K2CO3 in refluxing 50% aqeuous ethanol. KMnO4 has been utilized as a readily available, inexpensive oxidant for the in situ transformation of the initially formed dihydropyridine intermediate. K2CO3 also mediates the one-pot formation of chromeno[2,3-b]pyridines from reaction of salicylaldehyde or its analogs with malononitrile and thiol or thiophenols. Both of these conditions also work equally well under 50-fold scale-up conditions.Supplemental materials are available for this article.

  A novel, efficient and green Cu(II)/L-His@Fe3O4 catalyst has been applied successfully in the synthesis of heterocyclic compounds. The resulting catalyst was used in the synthesis of 2,3-dihydroquinazolin-4(1H)-ones, polyhydroquinolines and 2-amino-6-(arylthio)pyridine-3,5-dicarbonitriles as biologically interesting compounds. The present research is focused on investigation of recycling, reusability

  prepared via an ordinary or a magnetized process, are investigated in the synthesis of pyridine dicarbonitriles by one‐pot multicomponent reaction of 4‐methyl thiophenol, malononitrile, and aryl aldehydes. The results have shown that both prepared nano‐TiO2 exhibited high catalytic activities toward the synthesis of pyridine dicarbonitrile derivatives but the nano‐TiO2, which is prepared via a magnetized process

  通过4-甲基硫代苯酚，丙二腈和芳基醛的单锅多组分反应合成吡啶二甲腈，研究了通过普通或磁化方法制备的两种形式的纳米TiO 2的催化作用。结果表明，两种制备的纳米TiO 2对吡啶二甲腈衍生物的合成均表现出较高的催化活性，而纳米TiO 2是通过合成的方法制备的。磁化过程显示出更好的催化活性。此外，这种用于合成吡啶二甲腈的新催化方法可快速高产率地获得所需化合物，因此在室温下在有水存在的情况下进行简单的后处理即可。因此，该方法代表了与可用于合成吡啶二甲腈的其他方法不兼容的显着改进。

  Borax, an innocuous, inexpensive, and a naturally occurring material, very efficiently catalyzes the Knoevenagel condensation and Michael addition in domino fashion for the construction of highly functionalised pyridines, dienes, anilines and dihydropyrano[3,2-c]chromenes. The present protocol offers advantages in terms of higher yields, wide scope of substrates, operational simplicity, short reaction time, no requirement of workup or column chromatography, and easy access to a wide range of structurally diverse functionalized molecules of biological importance. Recycling of the catalyst and scaling up of the reactions are important attributes of this catalytic process.

  硼砂是一种无害、廉价且自然存在的物质，它以串联方式高效催化Knoevenagel缩合反应和Michael加成反应，用于构建高度功能化的吡啶、二烯、苯胺和二氢吡喃[3,2-c]色烯结构。目前的协议在产量、底物范围广度、操作简便性、反应时间短、无需后处理或柱层析以及易于获得结构多样且具有生物学意义的官能化分子等方面具有优势。催化剂的回收和反应的规模放大是该催化过程的重要特点。

  A novel basic ionic liquid, 1-(2-aminoethyl)pyridinium hydroxide, containing both Brønsted base and Lewis base sites has been used as an efficient catalyst for the synthesis of 2-amino-4-phenyl-6-(phenylsulfanyl)-3,5-dicyanopyridines. The condensation and oxidation tandem reaction of aldehydes, malononitrile, and thiols, performed in aqueous ethanol, afforded reasonable to good yields within 30–60 min. After the reaction, the catalyst could be recycled and reused. A possible mechanism to account for the tandem reaction is proposed. .
